Question

Complete the following vocabulary exercise relating to the level of structure in proteins. Match the words in the left-hand column with the appropriate blank in the sentences in the right-hand column.
1. Tertiary structure is achieved when a protein folds into a compact, three-dimensional shape stabilized by interactions between side-chain R groups of amino acids.
2. Quaternary structure is the result of two or more protein subunits assembling to form a larger, biologically active protein complex.
3. Primary structure is the sequence of amino acids in a protein.
4. Secondary structure describes the alpha-helices and beta-sheets that are formed by hydrogen bonding between backbone atoms located near each other in the polypeptide chain.

Answer 1

The correct match of words in the left-hand column with the appropriate blank is the following:

1. Primary structure of the protein is its nascent form by amino acid bonds. The bond is a covalent bond.

2. secondary structure is by alpha-helix of beta pleated structure. The presence of hydrogen bond.

3. Tertiary structure, also called functional structure, is the most important structure. It is a 3D structure, work as antibodies and enzymes.

4. Quaternary structure forms the complex protein, formed by interaction of two or more protein.

What are proteins?

Proteins are organic compounds that are made by multiple chains of amino acids.

There are four type of structure of protein: primary, secondary, tertiary, Quaternary.

Thus, the correct options are primary, secondary, tertiary and Quaternary structure.
